To `all fte/1.0m t may concern:

. Be it known that I, MARTIN `HnNDnR- SON, atcitiZen 'ofthe United States, residing at Manor, in the county of Ware and State of Georgia, haveinvented certain new .and useful Improvements in Attachments for llvaporatiiig `Kettles; and` I do hereby declare the following tobea lfull, clear., and exact description of` the invention, `such as will` enable "others skilled in `the .art to which it appertains to make .and usel `the same." t. i j `The presentinvention relates toevaporators for boiling ,down sapsor`sji`iices,iand has forits object the provisionof a novel Vand improved kettle attachment, for the purpose ofincreasing `the capacity -of the kettle and facilitatingthe removaloftlie scum and foreign matter from the juice `as itboils. j

A further object isl theprovision of such an attachment of novel form and vconstructed for attachment to the rim of thekettle or vat.

l/Vith tlieforegoing and other objects in view, which will be apparent as the description proceeds, the invention resides` in Ithe construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing `from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan View of the evaporator.

Fig. 2 is a section on the line 2-2 of Fig. 1.

The evaporating kettle or vat is indicated at K, and fitted on the rim thereof is an annular rim member 6, having a vertical wall. This member 6 is formed from a length of wood or other equivalent material which is bent into circular form, with the terminal portions 7 overlapping through an arc of about one third of the circumference of the member 6. The overlapping portions 7 are provided with an upwardly opening recess or opening 8, and said portions 7 are secured together at the opposite sides of saidk openino 8, by means of rivets-9 or the like. Tn order to strengthen the member 6 at the openinga brace rod 10 extends over the opening and has'downwardly bent terminals 11 driven between the portions 7-at the opposite sides of the opening, thereby strengthening the upper edge portion of the memsber 6 where it is weakened by the opening y A skimming and cooling trough 12 eX- tends radially from the member 6, being constructed` of sheet metal or similar material and havingthe side walls 13, inclined bottom 14., and the outer closed end 15. Theunner open portion of the trough 12 isiitted within the opening 8, with the side walls 13 extending across the side edges o fthe opening 8 and provided with eXtensions or flanges 16 bent to overlap the member onthe inside, and said extensions 16 are secured to the member 6 by means of nails 17 or other securing elements. The bottom 14 extends across the lower edge of "the opening 8 and has a downturned lip or flanges 18 overlapping the member 6 on the inside below the opening whereby the sap or Juice which drains back from the trough `willbe directed back into the kettle.

1 A strainer is located within the inner open end of the trough, and for this purpose, a row, of pins 19 are driven downwardly through the `bottom 12 into the portions 7 belowthe opening 8, for retaining in place a strainer 2O placed on the bottomv 14 of the"trou`gh against said pins. The strainer 20 may be made of a folded sack, sheet of fabric, or porous material with the strainer on the bottom of the trough extending from one side thereof to the other, at the inner open end.

The member 6 can be readily applied to the rim of the kettle, as seen in Fig. 2, and said member with the trough 12 will considerably increase the capacity of the kettle especially in view of the fact that the kettle can be filled up to the edge, and the niember 6 and spout 12 will retain the foam as the juice or sap boils. As the juice or sap boils, it rises, and the foam will iiow over into the trough 12 over the strainer 20, and in coming into contact with the metal, which is kept cool by the air, the foam will condense, and the condensed juice will flow back down the sloping bottom 14 of the trough, and pass through the strainer 20. This strainer will catch the scum and foreign matter, which can be readily skimmed out with a spoon or other instrument. This boiling over of the foam into the trough is practically continuous during the boiling of the juice or sap, providing a continuous straining of the foam, and thereby enabling the scum and foreign matter to be conveniently removed. The trough 12 being of sheet metal and extending to one side from the kettle, Will be cooled by the air, to condense the foam as it flows over the strainer into the trough, thereby keeping up the cir# culation through the strainer. `This saves considerable time and trouble in removing the skimmings, and results in a higher grade of syrup with much lessinanual effort, as well as increasing the output,

Having thus described the invention', what is claimed as newis n Y '1. An attachment for an evaporating kettle comprising an annular rim member to tit the rim of the kettle having an opening at one side, and a cooling and v` skim1ni`ng trough lextending to one side from the rim member and itted'and secured within said opening. f y Y 2. An attachment `for an evaporatin'g Akettle comprising an annular rim member to t the rim of the kettle having an 'opening at one side', aA cooling 'and skimming trough extending to one side from the rim member andfitted and secured within said opening, the .bottom of the trough being inclined to drain the sap or juice back into the kettle,

and a strainer within 'said'trough at the inner end thereof. 4 y l K, i

3. An attachment y for an evaporating kettle comprising an annular ,rimmemberto fit the rim of the kettle lhaving an opening yat one side, and fa cooling and y'skimming trough extending from said side of the 4rim and having its inner endrportion itted Within said yopenin'gand provided with viiange's overlapping the rim member on the interior thereof.

4. An attachment :tor an evaporating kettle comprising an annular rim member to it the rim of the kettle having an opening at one side, a cooling and skimming trough extending from said side of' the rimA member and having its inner end itted in said open ing, and pins driven downwardly into the rim member at the inner end ot said trough for retaining a strainer in the trough.

y Y5'. attachment for an evaporating k'ettle` comprising an annular' rim member to iit the rim 'of the kettle having an opening 'at one side, a Icooling and skimming trough extending from said side of the rim member and fitted and secured within said opening, and a brace rod extending across said opening and inner end of the trough and secured t'o therim member at the opposite sides of said opening.

6. An attachment for an evaporating kettle comprising an annular rim member to fit the rim of the kettle compri-sing a length of material having overlapping terminal portions, Said overlapping terminal )ortions having an opening, and a cooiing and skimming trough extending from the rim member and having its inner end portion fitted and secured within said opening.

testimony whereof I have signed my name to this vspecification in the presence of two subscribing witnesses.
